In spite of all the attention received by Magnifica Humanitas, focused on the relationship between human values and artificial intelligence, it also can be viewed within the context of the full range of social doctrine guiding the Catholic Church since the publishing of Rerum Novarum in 1891.
Note the intentional choice of name by Pope Leo XIV (who authored Magnifica Humanitas), following Pope Leo XIII (who authored Rerum Novarum).
The choice of name is deliberate. It implies that his pontificate will center on the Church aggressively defending human dignity and workers' rights.
Every encyclical since Rerum Novarum has elaborated a consistent body of doctrine known as the “social doctrine” of the church, compiled neatly in the document Compendium of the Social Doctrine of the Church.
The thread running through every encyclical is that the human person possesses an inalienable dignity and that no economic system, political ideology, technological or ecological issue can be evaluated apart from what it does to that dignity:
Rerum Novarum (1891) argues that workers are not a commodity and have the right to a just wage, the right to form associations and own property.
Quadragesimo Anno (1931) includes the principle that decisions should be made at the lowest competent level of social organization, to support human agency and creativity.
Mater et Magistra (1961) discusses human rights and responsibilities
Pacem in Terris (1963) argues that states, like persons, are subject to a moral order they did not create
Populorum Progressio (1967) argues that authentic economic development is not gross domestic product growth but the development of the whole person and every person
Octogesima Adveniens (1971) addresses the person in the modern city — uprooted from traditional communities, confronted with ideological pluralism, newly exposed to media and mass politics
Laborem Exercens (1981) argues that work matters not only because it produces goods, but because in working, the person expresses and develops themselves as a subject
Sollicitudo Rei Socialis discusses solidarity, a commitment to the common good
Centesimus Annus (1991) argues that markets are legitimate when governed by a strong juridical framework and embedded in a culture that prizes more than consumption and is shaped by concern for the common good
Caritas in Veritate (2009) insists that love (caritas) belongs in economic and social analysis as a principle of social architecture. He argues that the economy needs not only justice (what is owed) but gift (what is freely given beyond obligation)
Laudato Si' (2015) argues that the ecological crisis and the human dignity crisis are the same crisis. An economy and culture that exploits the natural world with indifference is animated by the same logic that exploits persons
Laudate Deum (2023) is about climate change and global governance
Dilexit Nos (2024) argues that persons are not bundles of preferences or economic actors but beings with an interior life oriented toward love
Magnifica Humanitas (2026) extends the principle of human dignity to the use of AI.
A persistent misreading of Catholic social encyclicals treats them as policy manifestos.
They are instead a platform of moral principles that guide policy reasoning without determining specific policy outcomes.
In other words, the encyclicals teach ends. They do not generally prescribe the means.
The principles most commonly discussed in social teaching include:
Human dignity: Every person, by virtue of being human, deserves to be treated as an end, never merely as a means
The common good: conditions that allow persons and communities to flourish
Subsidiarity: decisions should be made at the lowest level of social organization competent to make them effectively
Solidarity: persons and communities are genuinely responsible for one another
The Universal Destination of Goods: the goods of creation are destined for all persons
The Preferential Option for the Poor: in situations of conflict or scarcity, priority belongs to the needs of the most vulnerable.
The corollary is a high and demanding vocation for the laity. If the Church does not prescribe policies, then Catholic politicians, economists, lawyers, scientists, engineers, and citizens bear genuine responsibility for the quality of their prudential reasoning.
The Catholic tradition, outlined in Gaudium et Spes, does explicitly and formally hold that the determination of specific social, economic, and political policies falls within the proper competence of the laity, and that clergy, as clergy, have no special expertise in these matters.
Apostolicam Actuositatem (Decree on the Apostolate of the Laity) reinforces this, saying "the laity must take up the renewal of the temporal order as their own special obligation."
Christifideles Laici (1988) is perhaps the most fully developed treatment. The apostolic exhortation describes the laity's secular character as their "proper and peculiar character.” It is not accidental but essential to their vocation.
The temporal order (politics, economics, culture, science, the professions) is the specific field of lay apostolic activity, according to Octogesima Adveniens. Clergy and religious who involve themselves in direct political activity are, in an important sense, trespassing on a domain that is not properly theirs.
But there are nuances.
It does not mean clergy are forbidden from having opinions. Bishops and priests are citizens, often educated people, sometimes with relevant expertise in economics, law, or political philosophy quite apart from their ordination. A bishop who is also a trained economist has that economic competence as a person.
It does not mean the Church is silent on social matters. The entire tradition of social encyclicals demonstrates the opposite. What it means is that the Church's legitimate social teaching operates at the level of moral principles, not policy.
The Catholic tradition's formal position is both clear and demanding: clergy have genuine and important authority in articulating moral principles, forming conscience, and prophetically naming clear violations of human dignity.
The clergy has no special competence, and no legitimate authority, in determining the specific social, economic, and political policies through which those principles are imperfectly and provisionally embodied in historical institutions.
Magnifica Humanitas has to be read with all that in mind.
